The Infrared Pen represents a deceptively simple input tool whose real power lies in how elegantly it communicates with modern projectors and interactive displays. Rather than relying on physical touch sensors embedded in a screen, it leverages invisible infrared light to translate human gestures into digital actions.
Purchasing an Infrared Pen requires far more consideration than simply choosing a digital pointing tool. Compatibility and accuracy are the two defining pillars that determine whether the pen enhances productivity or becomes a source of frustration.
